Brucellosis, Rose Bengal test, Culture, PCR.


The objective of study was diagnosis of some Brucella spp. from human suspects and infection patients via methods of serology (Rose Bengal test) and culture. The PCR assay was investigated as a potential role in detection of some Brucella. Blood samples was used to detection common species like: Brucella melitensis and Brucella abortus from sick persons whom were suspected to be infected with brucellosis.

   Blood and serum tests were gotten from individuals whom were suspected of contamination with brucellosis, alluded to numerous doctor's facilities in various city of Baghdad (Karkh and Rusafa parts), which include: (General doctor's facility Mohammad Baqir Al-Hakim, Al-Shaheed Al-Sadder clinic, Al-Imam Ali (rest in peace) doctor's facility), and access to insights and maps in all Iraq areas from Ministry of Health/Communicable Disease Control Center, within the time period  of the research that lasted from (March to December of the year 2014) .  

A sum of 117 fringe blood tests was acquired from sick persons about whom there were suspects of contamination with brucellosis. The analysis of brucellosis was affirmed by clinical discoveries by utilizing exams of serological nature such as: Rose Bengal test, culture and Gram recoloring and distinctive biochemical exams. To build up a PCR system for conclusion of brucellosis, DNA extraction was done through utilizing a business pack, followed by PCR amplification by using two sets of primers: B4/B5 and IS711 B.melitensis and B.abortus.

The results were obtained as 70 (59.82%) specimens as affirmative outcome by RBT and 59 (50.42%) specimens were affirmative outcome by culture from the blood of sick persons. Once the PCR method had been used to blood specimens as, 30 (25.64) cases positive for Brucella species, and 20 (17.09 %) were positive for Brucella melitensis and Brucella abortus.

These outcomes demonstrate that sick persons were in contact with creature of domesticated animals that contaminated or associated disease with Brucella like: sheep, goat, cow and bison situated in epidemiological locales in Iraq ,particularly in Baghdad region over the  research time frame and indicated that blood culture technique is vital for the discovery of brucellosis in contrast with serological strategies (Rose Bengal test) for the analysis of brucellosis. The PCR strategy is prescribed as an other option to culture for the analysis of brucellosis, so PCR method gives quick finding of brucellosis, which is important to begin the process of curing of a particular sick person.
